Primal Energon

Primal Energon is an ancient and rarely seen form of energon. Existing in a liquid state, it is recognizable by its oily, kaleidoscopic appearance, and is only found either underground or as a consequence of mucking around with space and time. When ingested, it grants double the energy regular energon provides, but with the side-effect of infusing those who take it with the raw, bestial instincts of Cybertron's ancient life forms.

Notes

• Primal Energon was introduced in the Transformers Roleplaying Game's Decepticon Directive sourcebook, but its description and properties seem to make it an adaptation of the energon known as the "blood" of Trypticon as it was depicted in The Transformers: Monstrosity.
